普陀鹅耳枥星天牛发生规律及防治试验

Occurrence and Control of Anoplophora chinensis on Carpinus putoensis

  • 摘要: 普陀鹅耳枥Carpinus putoensis为国家一级保护野生植物,星天牛Anoplophora chinensis为害严重威胁普陀鹅耳枥的生存。2015—2017年,在浙江舟山对星天牛在普陀鹅耳枥上的发生规律、为害部位进行了调查研究和药剂防治试验。结果表明,在浙江舟山,星天牛在普陀鹅耳枥寄主上以一年发生1代为主,少数为三年发生2代,普陀鹅耳枥星天牛蛹室宽度为0.75 ~ 1.00 cm;普陀鹅耳枥星天牛的为平均害率最高为19.11%,为害平均距地高度为0.38 m(0.05 ~ 1.50 m),多数集中在距地高0.30 m以下的树干基部和距地高1.05 ~ 1.35 m的枝、干分叉处,其为害数分别占调查数的72.00%和17.00%;蛀孔处干、枝的平均直径为2.63 cm,其中直径在1.60 ~ 3.50 cm的干、枝占调查数的94%。采用40%乙酰甲胺磷、40%毒死蜱和3%噻虫啉3种药剂对普陀鹅耳枥星天牛不同方法防治试验表明,以树冠喷雾防治成虫效果最好,其中以3%噻虫啉的防治效果最佳,其防治效果达98.72%;40%乙酰甲胺磷、40%毒死蜱针筒注射虫道防治幼虫具有较好的防治效果,树干喷雾防治幼虫效果最差;3%噻虫啉对星天牛幼虫基本无效。多树种混交的营林方式是降低普陀鹅耳枥星天牛发生的有效手段,当普陀鹅耳枥在混交林建群树种的混交配比为1∶5、造林株行距为8 m×8 m以上时,对降低星天牛的发生具有显著效果,星天牛的为害率在4%以下。

     

    Abstract: From 2015 to 2017, observations were conducted on life habit, occurrence and damage of Anoplophora chinensis on Carpinus putoensis in Zhoushan, Zhejiang province. The results showed that C. putoensis has mainly 1 generation a year, few have 2 generations per three years. The oviposition scar has width of 0.75-1.0 0 cm. The average damage rate of A. chinensis on C. putoensis topped to 19.11%, with average damage height of 0.38 m (0.05-1.50 m), most of oviposition scars were at 0.30 m aboveground and 1.05-1.35 m aboveground, which accounted for 72% and 17% of the total ones. The average diameter of pecky branches and trunks was 2.63 cm. Experiment of 40% of Acephate, 40% of Chlorpyrifos and 3% of Thiazophos on control of A. chinensis showed that spraying on crown was the best way to control adult, especially the last pesticide had the best effect of 98.72%. Injection of 40% of Acephate or Chlorpyrifos into trunk had better control effect on larvae. Mixed forest of C. putoensis with row spacing 0f 8 m×8 m had the lowest occurrence of A. chinensis, with damage rate less than 4%.
